METHOD FOR DYNAMIC COMPENSATION FOR THE OFFSET ERROR OF AN ACQUISITION SYSTEM COMPRISING A CURRENT SENSOR

摘要

The present invention relates to a method for dynamically compensating for the offset error of an acquisition system comprising a current sensor (1) designed to measure or estimate the current passing through an actuator (6) of a electrical apparatus that is electrically supplied by an AC voltage, said acquisition system having a predetermined offset value, said method comprising the following steps: - determining a plurality of periodic temporal operating ranges (PT) of the actuator (6) in order to dynamically apply a compensation sequence (SC) for the offset error of the acquisition system, - executing the compensation sequence (SC) during any one among the plurality of determined temporal operating ranges (PT), the synchronization between the any one of the determined temporal operating ranges (PT) of the actuator (6) and the execution of the compensation sequence (SC) being performed using synchronization means comprising a synchronization module (7) designed to identify reference times (Ref) from the AC supply voltage (AC) of the sector.
